GeForce NOW is also an option for those who can't update.
oof this is a chonky game. Does this mean i need to clear out 150 gb worth of space? I'm only using a laptop
Yes. You could try to run it through an external ssd as well, that will set you around $50 - $100+ depending. Steam shouldn't have a problem with the external ssd, but it might be a bit weird. You're better off putting the game on your main hard drive and moving other files to an external drive/usb drive.
